Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997866, here are decompositions:

53 + 997813 = 997866
59 + 997807 = 997866
73 + 997793 = 997866
83 + 997783 = 997866
97 + 997769 = 997866
127 + 997739 = 997866
139 + 997727 = 997866
167 + 997699 = 997866

Showing the first eight; more decompositions exist.
